One night stand outside of Paris?

I'm looking for a delicious one night away from Paris, someplace involving a TGV ride + Avis, dinner and overnight. Am considering La Grenouillère, In De Wulf, Le Jardin de Plumes, but none really sing to me. Any ideas for a somewhat posh but not over-the-top dinner and bed? I do not want an interminable tasting menu but rather a somewhat shorter menu and not killer amounts of food...

Thanks, Peter. We are looking for something more, how do you say it, cutting edge, off beat. Besides the ones I mentioned, something like La Mare aux Oiseaux perhaps. Someone who has almost but not quite arrived, a work in progress so to speak.

Good call. We have stayed several times at Les Rimains, his magical guesthouse and were lucky to enjoy the main restaurant before it closed but not tried Le Coquillage. This is the right direction, but one couldn't call Roellinger someone who hadn't quite arrived.

I'm kicking myself around the block for never having made it to In De Wulf, and now Chambo brings to our attention that it's closing (December). I've never hyped it enough to cause husband to yell "Go for it!" We've two more shots at it this year.

I would not, based on one dinner at In De Wulf in December. It might be a lot better during the summer months. The guest room we stayed in was super, though, as was breakfast.

Interestingly we have rather often had the same experience at this level restaurant-with-rooms: loved the lavish breakfast delivered to our equally sumptuous room but found ourselves looking for "something more exciting" during dinner.

Maybe I should just stick with the premonitions that have held me back up til now.
